[Morphofunctional changes in the kidneys in venous stasis during early period and during recovery of blood outflow from the organ].
Short-term (3 days) 50% constriction of the left renal vein with the following recovery of outflow from the kidneys (30 days) was carried out on (180-210 g) white mongrel adult rats of both sexes. By means of light optical, electronmicroscopic and radioisotopic methods it was established that venous haemostasis in early period leads to the slowing-down of regional renal circulation and the development of dystrophic changes both in the wall of intrarenal veins and in the edge and cubical cells of proximal and distal departments of nephron. With the recovery of renal circulation from kidneys canal-vascular formation acquire normal morphological structure. Compensatory-adaptive processes in the separate parts are noted.
